Description

Technical Field

[0001] This utility model relates to the technical field of gas-fired steam generators, and in particular to a well-use heat exchange type gas-fired steam generator. Background Technology

[0002] A well gas steam generator is a steam injection device used in the thermal extraction of heavy oil in the petroleum industry. It generates high-temperature steam directly downhole by burning gas to reduce the viscosity of crude oil and improve its fluidity, thereby achieving efficient extraction.

[0003] In practical applications, existing gas-fired steam generators have relatively complete structures and functions, which can meet basic usage requirements. However, the following problems still exist:

[0004] In practical applications, when the gas is directly heated after combustion, the heat needs to be transferred from the combustion chamber to the water storage space through the annular plate and the outer wall of the tank. This heating method results in a wide heat diffusion range, which reduces the heating efficiency. At the same time, the heat cannot be evenly transferred to the interior of the water storage space. Heating from the outside to the inside will lead to uneven heating, which will affect the steam dissipation efficiency.

[0005] Therefore, this utility model provides a well-use heat exchange type gas steam generator. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a well-use heat exchange type gas steam generator.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a well-use heat exchange type gas-fired steam generator, comprising:

[0008] The base is rectangular in shape.

[0009] The tank body is fixedly connected to the top of the base;

[0010] A combustion frame, which is fixedly connected to the top of the tank;

[0011] A heat exchange evaporation assembly is disposed between the tank and the combustion frame. The heat exchange evaporation assembly includes an annular plate, the top of which is fixedly connected to the bottom of the combustion frame, and the bottom of which is fixedly connected to the base. A water storage space is formed between the annular plate and the outer wall of the tank. A steam outlet pipe is fixedly connected to one side of the annular plate near the top. A pump body is installed on the top of the base. The inlet and outlet ends of the pump body are respectively connected to an inlet pipe and an outlet pipe. The outlet pipe is connected to the water storage space.

[0012] A cover plate assembly is disposed on the top of the tank body. The cover plate assembly includes a cover plate body, and an external pipe is fixedly connected to the top of the cover plate body. An exhaust pipe is installed on the external pipe through a flange structure.

[0013] With the help of the heat exchange evaporation component and the heat-conducting fins, the heat inside the combustion frame can be evenly transferred to the water inside the water storage space, thus conducting heat evenly and heating the water evenly, thereby improving the overall evaporation efficiency. The cover plate component can discharge the exhaust gas after combustion inside the combustion frame.

[0014] Optionally, a rectangular insertion hole is provided at the top of the combustion frame, and a rectangular slot is provided above the rectangular insertion hole at the top of the combustion frame. A heat-conducting fin is inserted into the inner wall of the rectangular insertion hole, and the bottom of the heat-conducting fin is located inside the water storage space.

[0015] The heat-conducting fins are inserted from the inside of the rectangular insertion hole and then guided into the interior of the water storage space, so that the heat-conducting fins can evenly conduct heat to the water storage space.

[0016] Optionally, a rectangular card block is engaged with the inner wall of the rectangular card slot, and a rectangular connecting plate is fixedly connected to the top of the rectangular card block. The heat-conducting fin is fixedly connected to the inner wall of the rectangular connecting plate and the rectangular card block. An extension fin is fixedly connected to one side of the heat-conducting fin above the rectangular connecting plate. Heat-conducting holes are provided on the side walls of the heat-conducting fin and the extension fin.

This enables the heat-conducting fins to be securely engaged with the inner wall of the combustion frame. Simultaneously, the extension fins and heat-conducting holes enhance the heat transfer speed.

[0018] Optionally, a first screw hole is provided at the top of the rectangular connecting plate, and a second screw hole is provided at the top of the combustion frame. The inner walls of the first screw hole and the second screw hole are threadedly connected with threaded clamps.

[0019] The threaded clamp is fixed to the first and second threaded holes, thereby fixing the rectangular connecting plate to the inner wall of the combustion frame.

[0020] Optionally, the bottom of the base is provided with a wire-passing groove, and the inner wall of the wire-passing groove is provided with a double-lumen tube. The double-lumen tube is composed of an outer tube sleeved on an inner tube, and one end of the double-lumen tube passes through the bottom of the tank and the combustion frame and extends into the interior of the combustion frame.

[0021] The dual-lumen tube can deliver both combustion gas and combustion-supporting gas to the interior of the combustion chamber.

[0022] Optionally, an annular locking block is fixedly connected to the bottom of the cover plate, and an annular auxiliary plate is fixedly connected to the top of the combustion frame. An annular slot is provided on the top of the annular auxiliary plate, and the annular locking block is engaged with the inner wall of the annular slot.

A threaded rod is inserted into the inner wall of the first and second insertion holes, and a fixing nut is threaded to the bottom end of the threaded rod.

[0025] The threaded insert is inserted and fixed into the first and second insertion holes, thereby fixing the annular auxiliary plate and the cover plate.

[0026] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0027] By incorporating a heat exchange evaporation assembly, heat from the combustion chamber can be directed to the water storage space via heat-conducting fins. This uniformly heats the water, allowing it to evenly generate steam. The steam is then transported to the oil well via an outlet pipe, reducing viscosity, improving fluidity, and increasing extraction efficiency. Furthermore, a cover plate assembly allows exhaust gases from combustion within the combustion chamber to be directed to the outside via external pipes and a flue, aiding combustion. The cover plate assembly is also easy to install and remove, facilitating subsequent maintenance and replacement. Attached Figure Description
